This presentation discusses the classification of polymers. Polymers are large molecules built up by the repetition of small, simple chemical units held together by covalent bonds. Polymers can be classified based on their reaction to stress and temperature, mechanical strength and behavior, way of production, molecular arrangement, type of monomer involved, and morphology. The presentation covers common polymer types like thermoplastics, thermosets, elastomers, plastics, fibers, and discusses their linear, branched, or cross-linked molecular arrangements and crystalline or amorphous morphologies.
